Why R290 Is the Future of Greenhouse Dehumidification

The refrigerant inside your dehumidifier matters — for regulatory compliance, for energy costs, and for your environmental footprint. R290 (propane) is rapidly becoming the standard for greenhouse climate equipment in Europe and North America. Here's why.

The GWP Comparison

Why European Growers Are Leading the Switch

The EU F-Gas Regulation (EU 2024/573) mandates an aggressive phasedown of HFC refrigerants. By 2030, the EU must reduce HFC consumption to just 21% of 2015 baseline levels. For greenhouse operators, this means equipment using R410A or R134a will become increasingly expensive to service — and eventually impossible to replace.

R290 is classified as A3 (flammable) but with a charge limit of ~500g per circuit in most jurisdictions. GrowClimate's GROW-60, GROW-90, and GROW-120 portable dehumidifiers use R290A with charges well within safety limits, achieving the same dehumidification performance as larger R410A units with dramatically lower environmental impact.

Bottom Line

If you're specifying new dehumidification equipment for a greenhouse project in Europe or North America, R290 is the future-proof choice. It delivers equivalent or better energy efficiency, complies with current and upcoming regulations, and carries a GWP of just 3 — effectively zero climate impact from refrigerant leakage over the equipment lifecycle.
